Bill Self's Kansas Jayhawks came through with a convincing 77-59 victory over the rival Kansas State Wildcats on Wednesday night, but the respected coach wasn't in a jubilant mood afterward due to the actions of junior guard Brannen Greene.

With just seconds remaining in the game and the Kansas State players already starting to walk off the court, Greene dunked the ball to put an exclamation point on the win.

As seen in this video, courtesy of WIBW, Self labeled the decision as "classless" and apologized to Kansas State:

According to Matt Galloway of the Topeka Capital-Journal, Self didn't stop there, as he continued to blast Greene in a subsequent radio interview:

Brannen Greene, we've put up with him doing some stuff in the past, but that was probably the biggest d--k move I've ever had a player do during a game. To dunk the ball like that when the other team—even their players are going, 'How disrespectful to the game.' It certainly showed unbelievably poor sportsmanship.

Despite the fact that the No. 7 Jayhawks improved to 18-4 overall and 6-3 in the Big 12 with the win, Greene's dunk clearly gnawed at Self.

"I'm so pissed right now, that we represented the way we did at the end," Self said.

Wednesday night wasn't the first time Greene was involved in an incident, as the junior was suspended for six games earlier this season due to an argument over playing time.

The Juliette, Georgia, native is averaging 6.9 points and 2.3 rebounds in 14.1 minutes per contest this season.

Greene has yet to comment on the matter, and it is unclear if another punishment could be coming his way, but it is clear he'll be forced to play his way back into Self's good graces.
